Iraq’s newly elected parliament adjourned Tuesday without deciding on a new speaker.

The election of a speaker is the first step in forming a unity government, but the House of Representatives couldn’t maintain a quorum after most of the Sunni and Kurdish members walked out, the Associated Press reports.

With the country under attack by radical Sunni fighters aligned with the al-Qaida spinoff group, the Islamic State, Iraq’s politicians have been under pressure to form an emergency unity government.
